Gabriel has helped Brazil reach the Copa America final.
And Rivaldo believes his success in the Copa America could give him plenty of confidence to take back to the Etihad.
"Gabriel Jesus has impressed me. We all know that things didn't went well for Jesus at the 2018 World Cup, as he was a regular first choice player and didn't score a single goal," Rivaldo told Betfair.
"But Tite kept his confidence in the kid and Jesus has rewarded his manager. He is still a young player with great potential and time to evolve - he will have many more opportunities.
"Jesus had a tough season, losing some importance in the Manchester City team, but Guardiola will be happy seeing him shining for the Brazilian national team and gaining confidence for next season."
